Skull Mountain is located in the east of Wangjia Village, nearly 100 kilometers away from Wangjia Village, with a mountain character in its name, but it is actually a large village built in the valley.

Compared with the remoteness of Wangjia Village, the place where Skull Mountain is located is much more prosperous, and there is a pipeline that passes not far from the outside of the big village of Skull Mountain, which is the pipeline from Jiazhou Mansion, the southwestern capital of the Tang Kingdom, to the most remote Lanhu County.

As the most remote county in the southwest of the Tang Dynasty, Lanhu County naturally has the characteristics of a small border town, that is, small and poor. The combined population of the entire small town is not as large as that of a small town in a prosperous area of the interior. The sparse population and poor people made the business of this place extremely depressed, and few merchants would come here.

As a group of bandits, guarding such a poor county, you may not meet a passing merchant for ten days and half a month, so the life of Skull Mountain is actually not good, relying on robbing the nearby villages from time to time, this can barely afford to raise so many people in Skull Mountain.

Tang Yun wanted to come to Skull Mountain to have a look, after all, this place was a den of thieves, and there were people from three sects and nine ranks, and there might be some people with real skills hidden in it, and maybe there would be a chance to get more and better exercises.

With this thought, before the sun rose, Tang Yun went out of her body, flew through the sky, and flew in the direction of Skull Mountain, while her body was still asleep in the cave.

Tang Yun's Yuan Soul had grown to a limit after she had been nourishing her Innate True Qi day and night for several years, and the wind in the mountains could not shake her Yuan Soul, nor could the scorching sun at noon scorch her Yuan Soul.

It was precisely because he felt that his Yuan Soul was already strong enough that he would not be easily harmed, so Tang Yun decided to directly let the Yuan Soul go to Skull Mountain out of his body. After all, it is a distance of nearly 100 kilometers, and if you walk all the way on land, you will really have to delay a lot of time.

The Yuan Soul travel is different, the Yuan Soul can fly in the air, although it can't fly too fast, but it can bypass most of the obstacles on the ground and move forward in a straight line.

What's more, the speed at which the Yuan Soul flies is always much faster than the speed at which it travels on land.

Tang Yun's Yuan Soul flew in the direction of Skull Mountain three or four meters above the ground, the speed was not particularly fast, at best, it was just the speed of a fast horse running, and if you wanted to speed up again, you would have a feeling of powerlessness.

Not long after departure, the sun rose, and the spring air was very clear without excess water vapor and dust, which also made the sunlight appear extremely bright.

Under the light of the sun, Tang Yun didn't feel too much discomfort, the sunlight that was enough to burn her Yuan Soul to ashes at the beginning was no longer able to hurt her at all.

Flying more than ten kilometers, Tang Yun glanced at the sky, and suddenly had an idea, wanting to try how high his Yuan Soul could fly.

As soon as the idea came to mind, it quickly took root.

Tang Yun in her previous life had also taken a plane, but that feeling was completely incomparable to the feeling of the current Yuan Soul traveling freely, and her instinct to fly kept urging her to see higher places.

As soon as his mind moved, the invisible and shadowless Yuan Soul flew towards the sky high.

In Tang Yunyuan's perception, it was obvious that as the altitude rose, the temperature around him became lower and lower, and the wind became stronger and stronger, and when it reached about three kilometers above the ground, the temperature was already colder than the coldest time of winter on the ground.

However, at this height, Tang Yun also enjoyed a strange scene that could not be seen on the ground at all, some water vapor gathered rapidly under the influence of low temperature and impurities in the air, and these water vapors turned into a white cloud like cotton under her nose.

Looking at the cotton cloud, Tang Yun couldn't help but get into it curiously, but found that the sight was white, and it was difficult to distinguish even the upper and lower sides. Coming out of the clouds, looking at the white clouds and laughing a few times, she now likes this world full of miracles more and more.

Flying to a place seven or eight kilometers above the ground, the air that seemed calm on the ground set off a terrifying storm here, and the fast-flowing air flow became like a blade, but fortunately, the Yuan Soul was formless and substantial, if the body was here, I am afraid that in the blink of an eye, it would be torn to pieces by these violent air currents.

Although the air here is violent, but now Tang Yun, the Yuan Soul is extremely powerful, and it takes some effort to make the Yuan Soul stabilize in this level of storm.

Looking up at the sky, to Tang Yun's surprise, the sky that was originally blue had turned into a dark cyan color when viewed at this height.

"What's the situation?" muttered to himself, feeling that he still had the strength to continue rising, so he didn't stop, and between the turns of his mind, the Yuan Soul flew towards a higher place.

Ten minutes later, Tang Yun stopped, looking at the purple dome above his head with horror.

Just a dozen meters above her head, the air was dyed lilac, and the lilac air gave her a feeling of extreme danger, as if she would definitely die if she touched a point.

When she was out of her body for the first time, the sunlight had also given her such a feeling! Now that this feeling had reappeared, Tang Yun was very sure that the purple air was extremely dangerous.

At this moment, a wisp of pale silver lightning was born out of thin air in the purple air, flickering and then dissipating without a trace.

Looking at that ray of lightning, Tang Yun felt as if he had fallen into an ice cave, his whole body was chilling, and the lightning was like his natural enemy.

Tang Yun, who was startled by the silver lightning, no longer dared to explore the sky, but fell rapidly, until he landed less than 100 meters from the ground, and then stopped with a sigh of relief.

Looking up at the still blue sky, Tang Yun's heart was full of shock.

If she hadn't flown into the sky with her own eyes to see, she wouldn't have known until she died, it turned out that there was a purple dome hidden above the blue sky, and in that purple dome, an extremely dangerous silver lightning would be born.

Nature has infinite power and contains infinite secrets, and to explore these secrets, you need more power and a long enough lifespan.

After sighing, Tang Yun once again identified the direction and headed towards Skull Mountain.

This trip to the Yuan Soul, especially the trip to the high altitude, made Tang Yun clearly feel the difference between the Yuan Soul and the physical body.

If we want to make an analogy, we can compare this world to the ocean, the physical body is the boat floating on the ocean, and the soul is the person in the boat.

The stronger the body, the stronger the ship on the ocean, and the more comfortable a person can sleep in the boat. The stronger the soul, the more people in the boat have learned to be watery, and they can swim in the ocean, until finally they can even abandon the boat and survive in the ocean.

In fact, these are two completely different directions of practice for practitioners.

The soul raiser strengthens the Yuan Soul, and finally integrates his own seven spirits with the Yuan Soul, casting the Dao Foundation with the Yuan Soul, and the Purple Mansion World exists in the Yuan Soul, and since then the body has become a skin, and the Yuan Soul travels, and the world is free.

The practitioner strengthens his body, and finally fuses his own soul with the seven spirits, casting the Dao foundation with the seven spirits, and the purple mansion world exists in the body, and the body is strong and indestructible.

Both of these are the methods of immortality, Feng Shaohua and Ghost Qiu have also mentioned it to Tang Yun, but at that time, her realm was too low, and she could only listen to it as a story, until today, she traveled with the Yuan Soul, and only then did she really feel the difference between the Yuan Soul and the physical body.

After packing up her thoughts, Tang Yun found that although she had not obtained any treasures or adventures in her high-altitude adventure, her understanding of the path of cultivation had become much more transparent, and the feeling of being in the clouds and fog when she practiced in the past dissipated a lot.

Tang Yun knew very well that this encounter would not immediately improve her cultivation, but it would remove obstacles to her cultivation and make her have a clearer understanding of the path she was going to take next.

Temporarily putting aside the shock of the purple dome above the blue sky, Tang Yun flew intently in the direction of Skull Mountain. It wasn't until the sun was about to set that a road with tamped dirt finally appeared in front of Tang Yun's eyes.

The road is about two meters wide and covered with horseshoe prints and wheel prints, and it can be seen that the road is often walked by people and horses.

Floating over the road, he regained his bearings and flew south along the road.

After flying out only two or three kilometers, Tang Yun saw from high in the sky that there was a wooden watchtower hidden in a forest, and an archer wearing a thick linen cotton coat was standing on the watchtower and patrolling.

Seeing this watchtower, and then looking at the chest of the archer on the watchtower, and finding that there was indeed a skeleton symbol there, Tang Yun was also relieved, and finally did not go in the wrong direction.

Tang Yun, who was flying in mid-air, found that there was a hidden path extending from this watchtower to the valley in the distance, this path was difficult to find if it was searched on the ground, but it was clear from the sky.

Flying along this path into the valley, you soon saw a towering earth and stone gate, and a plaque with three big characters "Skull Mountain" was hanging directly above the gate, just like the mansions of those dignitaries.

Looking at this plaque, Tang Yun sneered, this group of thieves is obviously a group of turtles, but they have to learn the style of the nobles, and make such a plaque come out, so that a good den of thieves looks nondescript.

At this time, the door of the skeleton cottage was closed, but this did not make it difficult for Tang Yun, who was traveling in the Yuan Soul, and she flew in directly from the sky, and identified the highest and most luxurious mansion in the village.

Flying over the mansion, Tang Yun discovered that there was also a martial arts training ground in the middle of the mansion, and at this time, two men were sitting on the edge of the martial arts training ground drinking tea.

Originally, Tang Yun only wanted to find trouble with Long Aotian to see if there was a chance to get Long Aotian's cultivation method, and he didn't bother to pay attention to other people, but the words of the one with a full face and a beard among the two men aroused her interest.

"Why do I look so nonsense at the inheritance stone tablet of the Gangsha Yuan Shendao that Long Aotian obtained?"
